Education and Awareness: Providing clear, accessible information about the importance of epidemiological research and how it benefits public health can motivate parents to participate. 2. Building Trust: Establishing trust through transparent communication and ensuring data privacy can alleviate concerns and encourage participation. 3. Flexible Participation Options: Offering flexible scheduling and multiple ways to participate (e.g., online surveys, home visits) can accommodate parents' busy lives.
